A Study of PRT2527 in Participants With Advanced Solid Tumors
brief summary
This is a Phase 1 dose-escalation and confirmation study of PRT2527, a Cyclin-dependent Kinase 9 (CDK9) inhibitor, in participants with advanced solid tumors. The purpose of this study is to define the dosing schedule, and maximally tolerated dose to be used in subsequent development of PRT2527.
detailed description
This is a multicenter, open-label, dose-escalation and confirmation Phase 1 study of PRT2527, a CDK9 inhibitor, evaluating participants with selected advanced/metastatic sarcomas displaying a documented gene fusion, castrate resistant prostate cancer, hormone receptor positive HER2-negative breast cancer, advanced/metastatic non-small cell lung cancer, and solid tumors displaying MYC amplification. The study plan expects to evaluate approximately six dose levels of approximately 1-6 participants per dose level; however additional and/or intermediate dose levels may be explored. Taking into account pharmacokinetic and pharmacodynamic data from the preceding dose levels, the dose may be escalated until a dose limiting toxicity is identified. The total sample size will be approximately 30 patients for MTD and RP2D determination.
